I've had a strange experience when I moved a story into the to-do status on multiple JIRA Kanban boards. When a story is sent to the to-do status, JIRA then sends that story to the bottom of the JIRA plan it is associated with. When I move it back to the backlog, it returns to the ranking before the move in the plan.
Does anyone have thoughts on where the board's configuration is off, causing the rank to be impacted when a story is moved from one status to another?
